At their simplest case studies are customer success stories that can help persuade customers to buy from you.  They are typically considered to be one of the top three marketing tactics used by  B2B businesses to boost customer engagement.
 
So why are they so effective?

In short, because a carefully crafted case study conveys trustworthiness and credibility from the first page to the last.  They give  you an elegant, way of showing your potential customers how you can solve their problem without overtly selling and wrapped up in a compelling storyline they make for highly engaging promotional materials.

Storytelling can bring your product to life
 
Case studies are all about success stories. They describe how your company has solved a problem, overcome a challenge, or introduced a new and innovative service.
 
Unlike a white paper, a case study is a fairly short document, running at about 800-1000 words. The skill of the writer is to make each word count by  crafting a   compelling story to engage customers interest, connect with their pain points, point out the benefits of your product or service, and get them on board.
 
Social proof at its most powerful
 
A well-written case study is a powerful form of social proof. Not only does it tell the story of how a customer benefitted from your service  but it also lets you subtly weave in the details of your product right within the storyline.
 
Best of all readers expect a call-to-action.
 
To show just how effective a case study can be, recent research has shown that about 78% of B2B buyers turn to case studies when researching potential purchases. And if someone is willing to take the time to read through your case study, it follows that they will expect to see your call to action at the end.  It’s the natural next step to lead them towards the sale.
 

I've always been fascinated by the power of language to influence and persuade. So many years ago I trained as a Clinical Hypnotherapist and then as an NLP Practitioner and it’s been the bedrock of my business ever since.

One of the most useful skills health writers can learn from NLP is how to enhance written rapport to increase reader engagement. To do that, you need to capture your reader's attention right from the start.  That means using language patterns that suits the other person’s preferred communication style, whether their perception of the world around them is primarily visual, auditory or kinaesthetic / feeling.

Why is this important? 
​
Because the words that have the greatest impact and convey the most meaning are those most closely aligned to the readers own preferred representational system.

We all have one sensory modality that we give preference to over the others and it's useful to know what this is so you don't let that bias creep into your writing.

Consider the examples below and see if you can recognise your own language preferences.

Now that you know how to spot those visual, auditory and feeling words, have a look back through your latest blog posts, articles or information leaflets and make sure you use them all to make the greatest impact on your readers.

Whenever you are writing for your patients and customers, it’s important to choose words that will engage them strongly​ and deeply. Words that will paint a picture for them, strike a chord, or perhaps even touch their hearts.
